The Church of St Theodore in Jerash, Jordan, is an ancient religious site that bears witness to the historical significance of Christianity in the region. Located within the modern and ancient city of Jerash, which is one of the best-preserved Roman provincial towns in the world, the church is a part of the rich tapestry of archaeological wonders present there. This Byzantine-era structure is named after St. Theodore, a revered Christian martyr. The church was likely built around the end of the 5th century or at the beginning of the 6th century and showcases the typical architectural features of Byzantine ecclesiastical constructions, including detailed mosaics that depict patterns and inscriptions. The Church of St Theodore is one of several churches in Jerash's archaeological park, which itself is a sprawling complex that includes the famous colonnaded streets, forums, temples, and theatres of the ancient Greco-Roman city of Gerasa. Visitors to the church can marvel at the artistry of the mosaics and the craftsmanship of the stone columns and walls, as well as experience a sense of connection with the early Christians who once worshipped there.
